Master or background for printing (XP)

What is the best way to change a colored slide master (background) to have a lighter background for printing? In over words, Can I have a slide master for screen presentation and one to print the presentation? the change of slide master or background could be automatic?

Re: Master or background for printing (XP)

I have no experience of XP but with PP98 and PP2K I would not solve the problem in the way you are currently thinking.
In the File | Print dialogue there are two checkboxes - Grayscale and Pure Black and White. These are designed to assist when printing coloured slides on black and white printers. I am sure these will still be present in XP. Experiment with both and I believe you will find a solution which meets your requirements.
